That stay just tells me how important he is to Liverpool. 38 just wow.
It looks bad, and what we fundamentally know about football is that giving the ball away is a bad thing. It's even marked as a negative in Opta stats.
However, him giving the ball away from a cross is part of Liverpool's gameplan. Get the ball into an area where the defence have to (and will) win a header, then with the front press, win the second ball or put them under pressure to give the ball away in a much more dangerous position than the half way line.
The issue for Liverpool really is the front three look about as toothless as it gets at the moment and aren't doing enough. Trent will continue to cross and lose the ball regardless, that's how they play, they rarely score headers from crosses.
